Hey there, if you don't mind my butting in on your thread-
I've been having much the same problem lately (I bought my MB in mid-december, so it's definitely older than yours), and I tried to post a question here, but I don't think I could get anybody to answer since I was having trouble describing the noise and ended up getting reeeally longwinded
But your initial post describing the problem you had is actually really good for what seems odd with mine too, so I'd like to ask everyone what you think should be done when it happens with a slightly older, but still less than three-month-old MacBook.
Please bear in mind that I've already been to the reseller I bought it from (where I live you can't buy direct from the Apple representative, unless it's online which is kind of a long and overly complex procedure, so I bought it from the reseller the guys at the 'Apple Demo Center' recommended); I've also been to the Apple Demo Center itself. Both times (rather embarrassingly), the MB totally behaved and you couldn't hear a thing, but from the description, the guy at the Demo Center thingy said it sounded like just normal MB noise. I was still worried because it seems to have gotten noisier than it used to be, but he assured me it's just that it's sort of hitting its stride, as it were *shrug*
Any thoughts?
EDIT: forgot to add some info on the model. It's mid-level like the OP's (only older, bought in mid-december, 2007), so it's 2.2 GHz, with a 1GB RAM. I'm not very good at the under-the hood stuff in computers, but if you tell me where to look I could give any other info (probably!)
If you could help me out on this, I would seriously appreciate some opinions; the folks at the reseller's and the Demo Center said it's all fine, but then for some reason you couldn't hear the buzz when I was there, so I'm still not reassured all is well
It's starting to really encroach on my enjoyment of this otherwise lovely computer
